Question: "What is Christian ethics?"
Answer: Christian ethics is well summarized by Colossians 3:1-6: "Since, then, you have been raised with Christ, set your hearts on things above, where Christ is seated at the right hand of God. Set your minds on things above, not on earthly things. For you died, and your life is now hidden with Christ in God. When Christ, who is your life, appears, then you also will appear with him in glory. Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. Because of these, the wrath of God is coming."
While more than just a list of "do's" and "don'ts," the Bible does give us detailed instructions on how we should live. The Bible is all we need to know about how to live the Christian life. However, the Bible does not explicitly cover every situation we will face in our lives. How then is it sufficient for the all the ethical dilemmas we face? That is where Christian ethics comes in.
Science defines ethics as "a set of moral principles, the study of morality." Therefore, Christian ethics would be the principles derived from the Christian faith by which we act. While God's Word may not cover every situation we face throughout our lives, its principles give us the standards by which we must conduct ourselves in those situations where there are no explicit instructions.
For example, the Bible does not say anything explicitly about the use of illegal drugs, yet based on the principles we learn through Scripture, we can know that it is wrong. For one thing, the Bible tells us that the body is a temple of the Holy Spirit and that we should honor God with it (1 Corinthians 6:19-20). Knowing what drugs do to our bodies—the harm they cause to various organs—we know that by using them we would be destroying the temple of the Holy Spirit. That is certainly not honoring to God. The Bible also tells us that we are to follow the authorities that God Himself has put into place (Romans 13:1). Given the illegal nature of the drugs, by using them we are not submitting to the authorities but are rebelling against them. Does this mean if illegal drugs were legalized it would be ok? Not without violating the first principle.
By using the principles we find in Scripture, Christians can determine the ethical course for any given situation. In some cases it will be simple, like the rules for Christian living we find in Colossians, chapter 3. In other cases, however, we need to do a little digging. The best way to do that is to pray over God's Word. The Holy Spirit indwells every believer, and part of His role is teaching us how to live: "But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you" (John 14:26). "As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him" (1 John 2:27). So, when we pray over Scripture, the Spirit will guide us and teach us. He will show us the principles we need to stand on for any given situation.
While God's Word does not cover every situation we will face in our lives, it is all-sufficient for living a Christian life. For most things, we can simply see what the Bible says and follow the proper course based on that. In ethical questions where Scripture does not give explicit instructions, we need to look for principles that can be applied to the situation. We must pray over His Word, and open ourselves to His Spirit. The Spirit will teach us and guide us through the Bible to find the principles on which we need to stand so we may live as a Christian should.
